GAGE FOR CUTTER-HEADS.

' specification.

My invention relates to cutter-head gages, and the object of my invention is to provide an adjustable gage to be used for setting the knives on a cutter head for the purpose of adjusting the cutting edges so that they will be equidistant from the cutter-head. I attain this object by means of the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view of my gage. Fig. 2 is an elevation of a cutter-head with my gage applied thereto.

Similar letters refer to similar parts throughout both views.

The plate A is provided with a right-angled projecting block B, through which block I place the regulating-screw 0. Upon the plate A, I arrange a sliding adjustable plate lD. Preferably on the edge of the said plate D, I place the set-screw E, by means of which the sliding-plate D may be secured in any desired position on the plateA. I place theset-screw E preferably on the edge of the plateA for the reason that I wish to maintain the edge (1 of the plate D positively in position when the screw is set, preventing any rotary motion which might take place if the set-screw were on the top rather than at the edge of the plate D. The edge (1 is to be brought in contact with the cutting edge of the knife to be adjusted, and I make this edge (1 long in order that with a short knife in a cutter-head it will square the knife-blade with the edge of the plate D. From the projecting block B on the end of the plate A, I preferably graduate the plate A, as shown in Fig. 1 at H, the graduations being, preferably, one-sixteenth of an inch apart and the extent of graduation preferably one inch or more.

I show in Fig. 2 my gage in connection with the blade F of the cutter-head G. The

adjustable screw 0 is in contact with the cutter-head projected into the recess J in the cutter-head. The edgedof the plateDis in contact with the edge of the knife-blade F. The screws 0 and E are respectively set in position. The other knives of the cutterhead may be adjusted to correspond by using the gage in connection with them, respectively, in the manner shown in Fig, 2. When there is no recess J in the cutter-head adj acent to the blade F, the screw C is drawn sufliciently from the block B to allow the block B to engage the side of the cutterhead.

In the use of my gage I do not engage both sides of the cutter at the same time and am not interfered with by bolts or other construction of the knives, the cutter-head, or attachments, and I may readily use my gage in connection with any style of cutter-head and adjust the same without in any manner being inconvenienced because of projections orrecesses on the blade, cutter-head, or means for attaching the same.

For the purpose of causing the gage to be held in contact with the cutter-head after it has been placed in position I may magnetize the block B by rubbing the block with a magnetized bar of iron or in any suitable manner. so that when it is brought in contact with the cutter-head it will by magnetism be held in position in contact therewith.

IVhat I claim as my invention, and desire to secure by Letters Patent, is

1. An adjustable gage for cutter-heads; comprising a plate; a right-angled projecting block at the end thereof; a sliding plate adapted to reciprocate on that side of said first mentioned plate opposite that from which said block projects; an adjustingscrew in said block; a set-screw in said sliding plate.

2. An adjustable gage for cutter-heads; comprising a plate; one end of which is adapted to be placed beneath the projecting portion of a cutter-blade; a right-angled projecting block at the end of said plate eX- tending from the side of said plate opposite that upon which said cutter-blade is adapted to rest; an adjusting-screw in said block; a sliding plate upon the side of said first-mentioned plate that the cutter-blade is adapted torest upon; a set-screw in said sliding plate. 3. An adjustable gage for cutter heads; comprising a plate; a right angled projecting magnetized block at the end thereof; an adjusting screw in connection with said block; a sliding plate adapted to reciprocate on said first-mentioned plate along the side thereof opposite to that from which said block extends; a set screw in said sliding plate, substantially as described.
